The process of design and installation of our ASHP system was smooth and efficient. The whole team were pleasant, helpful and took obvious care of our property. I would have no hesitation in recommending them to others considering a like project.
David Goacher
They attended a hot water issue with my heat pump at short notice. Carried out thorough checks and quickly diagnosed and rectified the problem. There engineers were extremely helpful and polite. A company I can strongly recommend.

I cannot sing the praises of this company more highly; from specialist expertise in Air Pumps, Solar and traditional wet central heating to ease of booking and fair pricing - these guys should be your first and only call!!
Colin Waite
Great Service from Matt at Garry Hamilton Ltd. He serviced our Air Source heat pump and hot water system. Has a very good knowledge of the system and is very helpful answering any questions we have. Would recommend.

Great Company - Helpful, communicative and reasonably priced. They turn up on time, do a great service, and let you know exactly what needs doing and what doesn't.
We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
